Under the altered conditions of population, skill, and knowledge, the facility of life as carried on according to the traditional scheme may not be lower than under the earlier conditions; but the chances are always that it is less than might be if the scheme were altered to suit the altered conditions.
The group is made up of individuals, and the group's life is the life of individuals carried on in at least ostensible severalty.

The group's accepted scheme of life is the consensus of views held by the body of these individuals as to what is right, good, expedient, and beautiful in the way of human life.

In the redistribution of the conditions of life that comes of the altered method of dealing with the environment, the outcome is not an equable change in the facility of life throughout the group.

The altered conditions may increase the facility of life for the group as a whole, but the redistribution will usually result in a decrease of facility or fullness of life for some members of the group.

An advance in technical methods, in population, or in industrial organization will require at least some of the members of the community to change their habits of life, if they are to enter with facility and effect into the altered industrial methods; and in doing so they will be unable to live up to the received notions as to what are the right and beautiful habits of life.
Any one who is required to change his habits of life and his habitual relations to his fellow men will feel the discrepancy between the method of life required of him by the newly arisen exigencies, and the traditional scheme of life to which he is accustomed.
